but are they not also fighting the Taliban? From whence does this 'massive' local insurgency you speak come from. The Afghans don't want the Talibs back - and the only ones keeping them at bay at present are the international forces, because as you say the Afghans are "a feeding baby in his early stage, who doesn't have biting teeth, and legs to walk."
The International Forces will be leaving very soon...2 to 3 yrs I forsee. I wouldn't be too eager to see them go until the Afghan Army can take over.
